Extraosseous Ewing’s sarcoma, a case report on a rare diagnosis in an 80-year-old woman with a large abdominal mass

Abstract

Extraosseous or extraskeletal Ewing’s sarcoma is a very rare mesenchymal soft tissue malignancy. We report on a case of abdominal swelling in an 80-year-old woman caused by a large intra-abdominal EES. This case report illustrates that Ewing’s sarcoma can occur in adults and elderly, and highlights the importance of early diagnosis because of poor prognosis.
